If Shudder Occurs During TCC Apply, Release, and ECCC

If the shudder occurs while the TCC is applying, the problem can be within the transmission or the torque converter. Something is causing one of the following conditions to occur:

• The clutch is not engaging completely.
• The clutch is not releasing completely.
• The clutch is releasing and applying rapidly and continuously.

One of the following conditions may be causing the TCC Shudder to occur:

• Leaking turbine shaft/TCC seals
• A restricted release orifice
• A distorted clutch or converter cover due to long flexplate to converter bolts
• Defective friction material on the TCC plate
• Contaminated Transmission Fluid
